Particle size distribution (Granulometry)
Administrative data
Link to relevant study record(s)
- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions)
- Principles of method if other than guideline:
- The particle size distribution was determined by Image Analysis in accordance with the Council Regulation (EC JRC73260, nanomaterial). The test method is in all essential part identical with the OECD Guideline, Test no. 110, method B.
The pigment was dispersed in about 10 ml of distilled water by means of ultrasound for 1min with the power of 100W. Thus, agglomerates are destroyed forming single or aggregated particles. The particles are placed on a TEM grid and tested by high resolution scanning transmission electron microscopy (HR STEM Company: FEI, QS- No.: 02464; SOP 00013 Vers.2; Reference Material: UER3 922.00). - GLP compliance:
- no
- Type of method:
- microscopic examination
- Type of distribution:
- counted distribution
- Percentile:
- D50
- Mean:
- 81 other: nm
- Remarks on result:
- other: Migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.
- Percentile:
- other: 62%
- Mean:
- 1 - <= 100 other: nm
- St. dev.:
- 3.8
- Remarks on result:
- other: The quantity of 62 ± 3.8% of all particles with an ECD (equivalent circle diameter; Q0 ECD) are between 1 nm and 100 nm.
- Conclusions:
- 62 +/- 3.8 % of all particles of the measured test materialiron manganese trioxide based on the equivalent circle diameter (ECD) are between 1 nm and 100 nm. Iron manganese trioxide is a nanomaterial.
- Executive summary:
According to the EU definition iron manganese trioxide is a nano material. 62 +/- 3.8% of the particles have a equivalent circle diameter within the specification for nano materials.
Definition:
"Nanomaterials means a natural, incidential or manufactured material containing particles, in an unbound state or as an aggregate or as an agglomerate and where, for 50% or more of the particles in the number size distribution, one or more external dimensions is in the size range 1 nm -100 nm."

Description of key information
The test material iron manganese trioxide is considered as nanomaterial, as 62 +/- 3.8 % of all particles of the measured test material based on the equivalent circle diameter (ECD) are between 1 nm and 100 nm.
Additional information
Iron manganese trioxide is a nanomaterials, according to the EU recommendation of the definition of a nanomaterial 2011/696/EU, Official Journal of the European Union. The circle diameter is within the specification for nano materials. The particle size distribution was determined by Image Analysis in accordance with the Council Regulation (EC JRC73260, nanomaterial). The test method is in all essential parts identical with the OECD Guideline, Test no. 110, method B.
